To evaluate the effect of early breastfeeding cessation on incidence of diarrhea in a cohort of U.S. infants.
DESIGN, SAMPLE, AND MEASUREMENTS: A secondary data analysis was conducted using data from 2,340 mother-infant dyads participating in the Infant Feeding Practices Study II. We examined associations between duration of feeding type (e.g., exclusive breastfeeding [EBF], any breastfeeding [BF], formula feeding) and incidence of diarrhea before one year.
The sample included mother-infant dyads that were 86.2% White, 3% Black, and 5% Hispanic. Interruption of EBF before 3 months was significantly associated with higher odds of having diarrhea at 6 months (OR = 1.80, p value ≤ 0.01) and between 6 and 12 months (OR = 1.45, p ≤ .01). Breastfeeding interruption before 6 months was associated with higher odds of having diarrhea at 6 months (OR = 3.19, p ≤ .01). Formula feeding for ≥3 months was associated with higher odds of diarrhea between 6 and 12 months.
Exclusive breastfeeding for 3 months accompanied by any breastfeeding for 6 months provided the most protective effect against diarrhea. Public health interventions should address disparities in breastfeeding practices and provide support across clinical, workplace and community settings. Research should include more diverse population groups.
评估美国婴儿队列中早期停止母乳喂养对腹泻发生率的影响。
设计、样本和测量：利用参与婴儿喂养实践研究 II 的 2340 对母婴对的数据进行二次数据分析。我们研究了不同喂养类型（如纯母乳喂养[EBF]、任何形式的母乳喂养[BF]、配方奶喂养）的持续时间与一岁前腹泻发生率之间的关联。
样本包括 86.2%的白种人、3%的黑种人和 5%的西班牙裔母婴对。在 3 个月前中断 EBF 与 6 个月时（OR=1.80，p 值≤0.01）和 6 至 12 个月时（OR=1.45，p≤0.01）腹泻的几率显著相关。6 个月前中断母乳喂养与 6 个月时腹泻的几率更高相关（OR=3.19，p≤0.01）。配方奶喂养≥3 个月与 6 至 12 个月期间腹泻的几率更高相关。
3 个月的 EBF 加上 6 个月的任何形式的母乳喂养提供了对腹泻最有效的保护作用。公共卫生干预措施应解决母乳喂养实践中的差异，并在临床、工作场所和社区环境中提供支持。研究应包括更多样化的人群群体。
